1) A doctor presented initial experience using the new DxTerityTM universal radial curve catheters for transradial coronary angiography. 2) The DxTerityTM catheters were compared to the Optitorque® Tiger curve catheter on 40 patients, assessing manipulation, strength, kink resistance and ability to engage coronary arteries. 3) Results showed the DxTerityTM catheters performed equally well compared to the benchmark Optitorque® catheter across all evaluation measures, with no significant differences.

Initial experience with DxTerity™ universal radial curve catheters for transradial coronary angiography Gregory A. Sgueglia
Background
Very recently, the new DxTerity™ (Medtronic)
line of diagnostic catheters has been released
allowing higher lubricity, better manipulation,
improved strength and kink resistance

Initial experience with DxTerity™ universal radial curve catheters for transradial coronary angiography Gregory A. Sgueglia
Background
The availability of four different universal radial
curve shapes to engage both coronaries without
catheter exchange represents a unique
opportunity to shorten procedure and
fluoroscopy time and avoid radial artery spasm

Initial experience with DxTerity™ universal radial curve catheters for transradial coronary angiography Gregory A. Sgueglia
Methods
• Consecutive patients with an indication to
coronary angiography and a palpable radial
artery underwent a transradial coronary
angiography with a DxTerity™ universal radial
curve diagnostic catheter
• The DxTerity™ catheter performance was
assessed by a multidimensional evaluation and
compared to the Optitorque® Tiger curve
diagnostic catheter, which is considered a
reference tool for transradial coronary
angiography

Conclusions
The DxTerity™ universal radial curves
diagnostic catheters provided overall valuable
performance with no significant differences in
multidimensional evaluation compared to a
benchmark diagnostic catheter for transradial
coronary angiography
